Abstract

Agrogeotextiles (AGT) have potential for soil conservation, but limited information is available on effect of AGT on C sequestration and soil aggregation in Indian Himalayan region (IHR). Hence, the study was conducted on a 4% slope at Selakui, Dehradun in a maize-based cropping system where Arundo donax mats were used as AGT mats for soil conservation. Soil sampling was done in December 2021 after vegetable pea harvest and results indicated that in 0–15 cm soil depth, Maize + Arundo donax mat (10 cm thick) on 0.5 m vertical interval vegetable pea - wheat (M+A10D0.5-V-W) had ~23% higher total soil organic C (TSOC) in bulk soils than the control (M-W) plots. Plots with Arundo donax mats exhibited ~12% higher TSOC than plots without the mats. Plots under M+A10D0.5-V-W and maize-vegetable pea-wheat under bench terracing (M-V-W)B showed similar impacts on C sequestration. M+A10D0.5-V-W plots had ~36% greater macroaggregate and ~35% higher mean weight diameter (MWD) than M-W plots in the 0–15 cm soil depth. Microbial biomass C (MBC) enhanced by ~86% under M+A10D0.5-V-W over M-W in the 0–15 cm soil depth due to higher root biomass, root exudates and metabolizable C. Thus, microbial quotient (MQ) was also increased. Mean annual soil loss value of 2020–2021 and 2021–2022 ranged from 0.4 t/ha/yr to 2.9 t/ha/yr which was correlated with carbon management index (CMI) value. The CMI was ~38% higher in M+A10D0.5-V-W plots than M-W due to emplacement of Arundo donax mats, resulting in better soil aggregate stability. Thus, AGT application can be a potential practice for soil aggregation stability and C sequestration in the IHR. Conservation soil practices along with AGT are more profitable than conservation soil practices alone which had ~10% less benefit : cost ratio (B:C) on 4% land slopes of IHR.
